subretinal implant

A subretinal implant is a medical device used to help restore vision in people with certain types of retinal diseases, like retinitis pigmentosa. It is placed under the retina, the light-sensitive tissue at the back of the eye, and works by detecting light and converting it into electrical signals. These signals stimulate the remaining healthy cells in the retina, which then send visual information to the brain. This technology aims to improve vision and enhance the quality of life for those with significant vision loss.
